Modulation of whistlers

    An analysis of experimental data obtained at the Paratunka observatory (53.02° N, 158.65° E; L = 2.3), revealed an unusual form of whistlers, in which there are spectral lines symmetrical relative to a whistler. It is shown that this form is the most likely determined by amplitude modulation of whistlers by electromagnetic pulses with duration of about 1 s and filling frequency of 1.1 kHz. It is suggested that auroral electrojet, modified by the heating radiation of the HAARP stand (62.30° N, 145.30° W; L = 4.2), can be the emitter of such pulses.
